Marriage and specially arranged one is more nerve wrecking than anyone can imagine.So much of apprehension and anxiety around it.
Horoscope help you to score the overall match based on 8 categories
Varna (Work), Vasya (Dominance), Tara (Destiny), Yoni (Mentality), Maitri ( Friendships), Gana ( Basic insticts), Bhakoot (Love), Nadi (Health)
This would tell you detail about the nature of the persons individually and there attitude towards each other.
But horoscope cant tell the little nuances which Tarot can like feelings, or after you had the first talk with that person what is he thinking.Is he/she really interested or just a compromise.
What does he feel about you?Would he call back!! Is he being honest about himself?
Even stuff like what to wear for the first meeting :-)
Since you are in so much of mental turmoil sometimes simple choices about clothes can be a lot confusing!!
All in all you are trying to see a suitable match where there would be happiness , love and peace
and Tarot can really help!
